BYRON L. MORRISON, OF COLORADO SPRINGS, COLORADO.

HOSE-CLAMP.

To all whom it may concern:

Be it known that I, BYRON L. MORRISON, a citizen of the United States,residing at Colorado Springs, in the county of El Paso and State ofColorado, have invented a new and useful Improvement in Hose- Clamps, ofwhich the following is a specification.

This invention is a hose clamp and the object of the invention is a.clamp for the purpose of connecting a hose section to a coupling memberor discharge nozzle.

The invention consists in the novel features of construction hereinafterdescribed, pointed out in the claims and shown in the accompanyingdrawings, in which Figure l is a side elevation illustrating one use ofmy invention. Fig. 2 is a longitudinal section through Fig. 1. Fig. 3 isa transverse section taken through my clamp, through the hose, andthrough a coupling member. Fig. 4 is an end elevation of a splitclamping ring. Fig. 5 is a detail section taken transversely through anon-reduced portion of the clamping ring.

In these drawings 1 represents a section of hose to be clamped to acoupling member 2. Over said hose section is slipped a cut spring ring 3which is provided with a plurality of spaced transverse grooves 4, saidgrooves reducing the thickness of the ring and the non-reduced portionsare circinnferentially threaded as shown at 5. The ring is cut at 4-said out being preferably made through the longitudinal center of one ofthe grooves i. The clamping ring as a whole is tapered, the threadsadjacent the outer end of the coupling member being formed upon thethickest portion of the ring as will be obvi ous from an inspection ofFig. 2. After the ring has been placed in position by slipping it overthe hose it is clamped upon the hose and locked in position by a nut 6which is threaded upon it. It will be obvious that by reason of thetapering of the ring the nut 6 Specification of Letters Patent.

will bind the same tightly upon the hose clamp as it is screwed inplace, and the hose section is held tightly between the portion of thecoupling member 2 over which the hose is slipped and the spring clampingring 3. It will also be obvious that the grooves 4 may be of any equalnumber, according to the size of the clamping ring or according to thewidth of the grooves and of the various threaded portions.

In the drawings I have shown a ring having four transverse grooves andfour nonreduced threaded portions, but it will be obvious that byreducing the width of these portions siX of each may be employed withoutin any way changing the operation of the device, and it will also beobvious that the looking nut 6 may be either rounded or roughened to beturned by the hand, or if desired it may be a polygonal nut to be turnedwith a wrench.

The split ring 3 is provided with a plurality of interior ribs 7transversely arranged with respect to the outer threads, and oppositewith respect to the grooves 4, so that said ribs are formed upon thethick or nonreduced portions of the ring, the Object of these ribs beingto provide biting surface for engagement with the hose section and toprevent the clamping ring turning upon said section.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is

A tapering split ring circumferentially threaded, said ring having aplurality of transverse grooves on its outer face cutting through saidthreads, and having interior, transverse ribs out of alinement with saidgrooves.
